"When the shamans stop dancing and life in the rainforest loses its balance, the sky will collapse and come to crush everything".

Davi Kopenawa, a tribal leader and spokesman for the Yanomami, has been fighting relentlessly against the colonization of his land for 40 years. He warns Westerners that when the sky collapses, they too will be crushed. Why don't they listen?
